Periodic Acid- Schiff (PAS) Stain
This kit is for staining bone marrow and blood cellsmear.
PAS Stain is based on the principle of periodic acid-Schiff reaction. Periodic acid can oxidize Ethylene Glycol
(-CHOH-CHOH) contained in glycogen polysaccharides of cells to turn into dialdehyde (-CHO-CHO).
Subsequently, aldehyde will react with colorless Fucshin to form a red-fuchsin compound incytoplasm.
